Answer:
- the pressure will decrease
(volume is doubled ,the pressure reduced by half).
Step-by-step explanation:
P_1 V_1=P_2 V_2
This equation shows that, as volume increases, the pressure of the gas decreases in proportion.
Similarly, as volume decreases, the pressure of the gas increases.
Answer:
C -0.6
Step-by-step explanation:
2- -7 = 9
-2 - 13 = -15
9/-15 = -0.6
Supplementary angle must add up to 180 so the supplement will be 108 degrees. 180-72=108.
Answer:

Step-by-step explanation:

First, we expand the equation using the distributive rule:

Hence, 
Simplify: 
Add like terms:

Subtract 13 from both sides: 
Divide both sides by -8:

Answer:
6
